John Webster describes the "Five Freedoms" that ought as far as possible to be accorded to the animals we use either for companions, scientific research or food. He is particularly strong writing about farming practices. The wise warnings about HOW to bring about change for the better, how to determine what IS better and how to, most importantly, avoid legislating for change that will actually make things worse is instructive.
The book is written with charm and humour, not easy considering the grim subject matter, and with compassion towards those who are involved in keeping animals as well as towards the animals that they keep.
I work in animal welfare, and I have found the various formulae he provides for measuring animal suffering EXTREMELY helpful in deciding what is going wrong in any particular situation which means animals are subjected to unacceptable suffering. In addition the provision of a code, which is now internationally accepted, as being a way to judge the welfare of animals, and also to plan for their future welfare is extremely helpful.
For example, I recently helped a journalist, who was investigating allegations of welfare abuses at a uinversity (in Greece) herd of rare horses. The university would not allow a horse "expert" to visit, but accepted a journalist, who they thought would accept their rationale for any problems that had been reported. Using Mr Webster`s criteria we were able to make a list of easily identifiable welfare concerns, and she was able to make a score for the horse care using this, and so able to make a balanced evaluation of what she saw, and to write an article that directly influenced the university to make changes that improved the welfare of the animals, so that they could avoid public outcry.
There is no "bunny hugging" in "Animal Welfare". But there is plenty of hard facts and common sense and careful research, which must make an enormous difference to the lives of the animals John Webster has written this book to protect. This book was published in 1995. Much of the public concern for the life of farm animals which is now so much in the news can be directly attributed to the writings of John Webster. As the Greeks say: "Bravo tou!"
